# Calculating Inclination of an Air Hockey Table

• Aiko
In summary, the conversation discusses a physics student playing with an air hockey table and her observations and calculations regarding the table's inclination. The student concludes that the table is not level based on the puck's movement and its constant velocity. The conversation also touches on the net force acting on the puck and how gravity affects it.

## Homework Statement

A physics student playing with an air hockey table (a frictionless surface) finds that if she gives the puck a velocity of 3.86 m/s along the length ( 1.79 m) of the table at one end, by the time it has reached the other end the puck has drifted a distance 2.40 cm to the right but still has a velocity component along the length of 3.86 m/s. She concludes correctly that the table is not level and correctly calculates its inclination from the above information.

## The Attempt at a Solution

I don't know how to relate velocity to force. The velocity is constant so all net force equations equal to zero. I have no clue how to really start.

No there is a net force which pulls the puck to the right as it reaches the end of the table. The reason why the net force (gravity) doesn't affect the velocity of the puck is because it acts sideways to the velocity of travel of the puck, much like in circular motion.

If I set the coordinate system on the puck (which is on an incline plane), the force of gravity would be the only force acting on it in the x-direction, thus why it moves. Would it equal to zero or ma? It has a constant velocity in one direction.

## 1. What is the angle of inclination?

The angle of inclination is the angle between a horizontal line and a slanted line or surface. It is also known as the tilt angle, slope, or gradient.

## 2. How is the angle of inclination measured?

The angle of inclination is typically measured in degrees using a protractor or other measuring tool. It can also be calculated using trigonometric functions.

## 3. What is the significance of finding the angle of inclination?

The angle of inclination is important in many fields, including engineering, geology, and astronomy. It can help determine the stability of structures, the angle of a slope, and the position of celestial bodies.

## 4. How do you find the angle of inclination of a line?

To find the angle of inclination of a line, you need to know the values of the vertical and horizontal components of the line. Then, you can use the inverse tangent function (tan-1) to calculate the angle.

## 5. Can the angle of inclination be negative?

Yes, the angle of inclination can be negative if the line or surface is leaning downwards to the right. In this case, the angle would be measured in a clockwise direction from the positive x-axis.
